This invention relates to improvements in wing window holders for locomotive cabs.

It is frequently necessary for locomotive engineers to protrude their heads through the side windows of the locomotive cab in order to obtain a better view of the roadway. lVhen the engine is traveling at high speed cinders and dustparticles fly rearwardly at high speed and if they strike the eye of the engineer they are liable to cause serious injury and even when such cinders strike the face at any point they cause pain and discomfort.

In order to protect the engineer and the fireman from the disagreeable and harmful efi'ects of flying cinders and dust, it is customary to provide engine cabs with adjustable wing windows that can be folded forwardly against the outer'surface of the cab when not in use and which may be adjusted so as to extend perpendicularly outward when in use so as to serve as a windshield that protects the engineer or the fireman as the case might be. These wing windows have been held in adjusted position by various means among which may be mentioned hooks and eyes. It is obvious that wing windows should be held in adjusted position by some means that will hold them firmly and which will prevent rattling.

It is the object of this invention to produce a simple device that shall be particularly well adapted for holding loco-motive cab wing windows in adjusted position and which shall be so constructed that it can be readily applied and which shall be strong and easily adjusted.

Thisinvention, briefly described, consists of a hinge-like member of peculiar construction one part of this member may be of the same shape and size as an ordinary butt hinge and the other cooperating member is preferably formed from cast metal or from a piece of sheet metal of quadrant shape and which is provided with lugs extending at right angles to the plane of the member and adapted to engage the upper end of the wing window in a manner that will hereinafter be explained.

Having thus briefly described the inven- Serial No. 318,810.

tion,the same will now be described in detail and reference for this purpose will be had to the accompanying drawing in which the preferred embodiment of the invention has been illustrated, and in which:

Fig. 1 is a side elevation of a locomotive cab showing the wing window in operative position;

Fig. 2 is an end view of a locomotive cab showing the wing window in operative position; I

w is a view taken on line 3-8, Fig. 2, and shows the wing window held in operative position by means of my improved holder;

Fig. 4 is a section taken on line Irl,

in Fig. 4-, but shows the window in inoperative position; and

Fig. 6 is a section taken on line 6-6, Fig. 5 showing holder in the position it occupies when holding the window in inoperative position.

In the drawing numeral 1 designates a lo comotive cab which is provided with a win- 5 is a view similar to the one shown dow opening 2. The opening can be closed by means of a sliding window 3 that can be moved forwardly for the purpose of partially opening the window opening. Secured to the rear end frame 3? of the window by means of hinges 4 is a wing window 5. Although the wing window has been shown as secured to the window sash, it may be secured to a vertical supporting member rigidly connected with the cab and located in approximately the position occupiedby the rear vertical member 3 of the window frame in Fig. 1. The wing window can be rotated about its hinges into the position shown in Figs. 5 and 6 in which it lies substantially parallel with the window, or to a position like that shown in Figs. 2,' 3 and 4 in which it extends perpendicular to the plane of window frame 1, and which will be referred to as the inoperative position.

The holder that is employed for holding the wing window in its operative and/or its inoperative position is formed from two pieces of metal which have been designated by numerals 6 and 7 that are connected by a hinge pin 8 in the same manner as an ordinary hinge. The part of the holder that has been designated by numeral 6 corresponds in shape and size to the corresponding part of an ordinary hinge while the part has been designated by numeral 7 is much larger, and is provided on its lower side with spaced projections 9, 10, 11 and 12 which are so spaced that they will engage the upper end of the wine window and hold it in any one of three positions. Lug 9 is provided with a hook portion 13 that is adapted to engage underneath the lower edge of plate is and is so located that it will latch the wing window in inoperative position (Figs. 5 and 6). Lugs 10 and 11 have their adjacent sides spaced such a distance that the upper end of the window will be received between them and are so located that when the window is located between these two lugs it will extend outwardly at right angles to the window 3 in the manner shown in Figs. 1, 2, 3 and l. Lug 11 is triangular and it is spaced from lug 12 a div tance equal to the thickness of the wing window frame and when the wing window is located between these two lugs, it will occupy the position indicated by the dot and dash line in Fig. 4:. Part 7 is also provided with a curved portion 15 that affords a convenient grip for raising the part 7 when the wing window occupies the position shown by dotted lines in Fig. 4c. 4

WV hen the wing window is in use it occupies a position at right angles to the plane of win dow 8 as indicated by full lines in Fig. 4:, or it may be rearwardly inclined as when it occupies the dotted line position in Fig. 3. As the upper end of the wing window is located between adjacent surfaces of lugs 10 and 11 or 11 and 12, it will be securely held in place and can be moved only by raising member 7 to the position indicated by dotted lines Fig. 6. When the wing window is inoperative, it is rotated to a position in which it is parallel with window 3 and is securely held in this position by the action of lug 9. The hook 13 serves as a protective means that prevents the accidental raising of member 7 which would release the wing window.

In the embodiment illustrated and described, the preferred embodiment has been shown as formed from cast metal but it is evident that it may be made from sheet metal as well and can possibly be constructed from wood. Lugs 9, 10, 11 and 12 can be of any shape as long as they are properly spaced and located to hold the wing window in the desired positions.

The holder described above is extremely simple and can be quickly applied to any cab equipped with wing windows and will securely hold the window in adjusted position. As a rule only two positions are necessary for the wing window but the invention has been shown and described as constructed for three positions. It is evident, however, that by providing a smaller or a larger number of projections, it is possible to hold the wing window in any desired number of different positions.

Having described the invention what is claimed as new is:

1. A latch for holding a pivoted member in any of a plurality of angularly related positions, comprising a device formed from two separate parts hingedly connected, one of said parts being adapted to be secured to a stationary support adjacent the top of the pivoted member, and the other part being formed from a flat metal plate provided with three downwardly projecting lugs adapted to engage the upper end of the hinged member, two of said lugs forming a pair located near one edge of the flat member and the other being located near the other edge.
